Abstract
A method of manufacturing, by hot pressing, a dense and mechanically machinable ceramic body starting from a boron nitride-base ceramic powder which also contains a sintering aid in the form of boron oxide. The content of sintering aid, preferably in the form of material which, per se or in cooperation with existing boron oxide, forms glass, is corrected to a content of between 3 and 10 percent by weight. The ceramic powder is compacted and consolidated at a temperature of between 500 and 1500 DEG C and a pressure of between 50 and 300 MPa, into a body with a density amounting to at least 90 % of the theoretical density.
